目前的有源矩阵有机发光二极体(Active-matrix organic light-emitting diode，AMOLED)屏幕在手机的运用越来越广泛，对比传统液晶显示器(Liquid Crystal Display，LCD)，AMOLED屏幕非常薄,并且可以在屏幕中集成触摸层,所以在做超薄机方面,它更有优势。AMOLED自发光,单个像素在显示黑色时下不工作,显示深色时低功耗。所以AMOLED在深色下省电,并且具有传统LCD几百倍。AMOLED具有一定的柔韧性,比玻璃基板的LCD屏幕不易损坏。因此AMOLED的供电也有别于薄膜场效应晶体管LCD(Thin Film Transistor，TFTLCD),OLED需要在正负极上施加一定电压才能发光，AMOLED的正负电压需要用特殊的DCDC来供电。目前AMOLED采用的驱动电路，一般采用PMIC供电。PMIC将传统的多路输出电源封装在一颗芯片内，使得多电源应用场景高效率更高。一般具有多个直流至直流变换器(DC-DC converter)和多个低压差线性稳压器(Low dropout voltage，LDO)。The current active matrix organic light-emitting diode (Active-matrix organic light-emitting diode, AMOLED) screen is more and more widely used in mobile phones, compared with traditional liquid crystal display (Liquid Crystal Display, LCD), AMOLED screen is very thin, and The touch layer can be integrated in the screen, so it has more advantages in making ultra-thin machines. AMOLED is self-luminous, a single pixel does not work when displaying black, and low power consumption when displaying dark color. So AMOLED saves power in dark color, and has hundreds of times of traditional LCD. AMOLED has a certain flexibility and is less damaged than LCD screens with glass substrates. Therefore, the power supply of AMOLED is also different from thin film field effect transistor LCD (Thin Film Transistor, TFTLCD). At present, the driving circuit used by AMOLED generally adopts PMIC power supply. The PMIC encapsulates the traditional multi-output power supply in one chip, which makes the multi-power supply application scenario more efficient and efficient. Generally, there are multiple DC-DC converters (DC-DC converters) and multiple low dropout linear regulators (Low dropout voltage, LDO).

目前，终端上的AMOLED的驱动电路的使用和布局还是有待提高，主要存在如下缺陷：1)使用集成PMIC，成本高。2)集成PMIC精度相比单独LDO驱动，精度低。3)PMIC布局空间大。4)PMIC功耗大。5)PMIC可靠性低。6)目前的PMIC兼容性非常不好。At present, the use and layout of the driving circuit of the AMOLED on the terminal still needs to be improved, and there are mainly the following defects: 1) The use of an integrated PMIC is costly. 2) The precision of the integrated PMIC is lower than that of the single LDO driver. 3) PMIC layout space is large. 4) PMIC power consumption is large. 5) PMIC reliability is low. 6) The current PMIC compatibility is very poor.

因此，为了克服上述缺陷，本申请实施例提供了一种电源装置、电子设备及供电方法，能够精简用于为AMOLED供电的电源驱动，从而减少成本。Therefore, in order to overcome the above-mentioned defects, the embodiments of the present application provide a power supply device, an electronic device, and a power supply method, which can simplify the power supply driving for powering the AMOLED, thereby reducing the cost.

作为一种实施方式，主控模块200包括第一控制端ESWIRE和第二控制端ASWIRE。As an implementation manner, the main control module 200 includes a first control end ESWIRE and a second control end ASWIRE.

主控模块200用于根据所述第一控制端ESWIRE接收到的第一控制信号控制所述第一供电模块110输出第一电压V01以及控制所述第二供电模块120输出第二电压V02。作为一种实施方式，第一控制信号可以是外部输入的电压信号，也就是说，可以预先设定第一控制信号的有效电平，即在第一控制信号为有效电平的时候，主控模块200可以认定该第一控制信号有效，即控制第一供电模块输出第一电压以及控制所述第二供电模块输出第二电压，其中，第一控制信号可以是一个高低电平交替变化的脉冲信号。于本申请实施例中，主控模块200在检测到所述第一控制端ESWIRE接收到的第一控制信号为指定电平的时候，控制所述第一供电模块110输出第一电压V01，其中，该指定电平可以是高电平或低电平，具体地，可以依据实际使用而设定。于本申请实施例中，该指定电平为高电平。The main control module 200 is configured to control the first power supply module 110 to output a first voltage V01 and control the second power supply module 120 to output a second voltage V02 according to the first control signal received by the first control terminal ESWIRE. As an implementation manner, the first control signal may be an externally input voltage signal, that is, the effective level of the first control signal may be preset, that is, when the first control signal is at an effective level, the main control The module 200 may determine that the first control signal is valid, that is, control the first power supply module to output the first voltage and control the second power supply module to output the second voltage, wherein the first control signal may be a pulse with alternating high and low levels Signal. In the embodiment of the present application, the main control module 200 controls the first power supply module 110 to output the first voltage V01 when detecting that the first control signal received by the first control terminal ESWIRE is at a specified level, wherein , the specified level can be a high level or a low level, specifically, it can be set according to actual use. In this embodiment of the present application, the specified level is a high level.

则主控模块200在检测到第一控制端ESWIRE接收到的第一控制信号为高电平的时候，控制第一供电模块110输出第一电压V01，然后，再根据该第一控制信号处于指定电平的持续时长控制第二供电模块120输出第二电压V02。作为一种实施方式，该指定电平的持续时长可以通过对第一控制信号的脉冲计数的方式统计得到，例如，该第一控制信号为周期性的脉冲信号，则每个周期内的高电平的持续时长是已知参数，从而统计脉冲的个数，进而再将脉冲个数和该已知参数相乘，就能够得到该指定电平的持续时长。作为另一种实施方式，也可以是在检测到第一控制信号处于指定电平的时候，启动计时器，即该计时器以主控模块确定第一控制端接收到的第一控制信号为指定电平的时刻为起点，开始计时，从而通过计时器的计时能够确定第一控制信号的电平处于指定电平的时间长度，即持续时长。Then the main control module 200 controls the first power supply module 110 to output the first voltage V01 when it detects that the first control signal received by the first control terminal ESWIRE is at a high level, and then, according to the first control signal, is in a specified state. The duration of the level controls the second power supply module 120 to output the second voltage V02. As an implementation manner, the duration of the specified level can be obtained by counting the pulses of the first control signal. For example, if the first control signal is a periodic pulse signal, the high voltage in each cycle The duration of the level is a known parameter, so the number of pulses is counted, and then the number of pulses is multiplied by the known parameter to obtain the duration of the specified level. As another implementation, it is also possible to start a timer when it is detected that the first control signal is at a specified level, that is, the timer uses the first control signal received by the first control terminal as determined by the main control module as the specified level. The time of the level is the starting point, and the time is started, so that the time length for the level of the first control signal to be at the specified level, that is, the duration time, can be determined through the time measurement of the timer.

具体地，结合图2说明主控模块200根据所述第一控制端ESWIRE接收到的第一控制信号控制所述第一供电模块110输出第一电压V01以及控制所述第二供电模块120输出第二电压V02的具体过程。Specifically, referring to FIG. 2 , it is described that the main control module 200 controls the first power supply module 110 to output the first voltage V01 and controls the second power supply module 120 to output the first voltage V01 according to the first control signal received by the first control terminal ESWIRE The specific process of the second voltage V02.

Then the first voltage V01 can supply power to the source of the triode. In addition, the first voltage V01 can also supply power to other electrical components, which can be chips or active devices in an electronic device. Specifically, please refer to the following embodiments of the electronic device.

主控模块200检测到第一控制端ESWIRE被拉高的时候，开始记录该第一控制端ESWIRE被拉高的持续时长，即第一控制端ESWIRE接收到的第一控制信号持续为高电平的时长，若所述持续时长大于指定时长，则控制所述第二供电模块120输出第二电压V02。其中，该指定时长可是预先设定的一个时间长度，在持续时长大于指定时长的时候，发送第二指令至所述第二供电模块120，第二供电模块120响应该第二指令，输出第二电压V02。作为一种实施方式，该指定时长可以是10ms，因此在第一控制端ESWIRE被拉高10ms之后，第二供电模块120内部的降压或升压斩波器(buck-boost converter)启动，然后，利用第二电感L2周期性能量存储和释放，输出第二电压V02。When the main control module 200 detects that the first control terminal ESWIRE is pulled high, it starts to record the duration that the first control terminal ESWIRE is pulled high, that is, the first control signal received by the first control terminal ESWIRE continues to be at a high level. If the duration is longer than the specified duration, the second power supply module 120 is controlled to output the second voltage V02. The specified duration may be a preset duration. When the duration is greater than the specified duration, a second command is sent to the second power supply module 120, and the second power supply module 120 responds to the second command and outputs a second command. Voltage V02. As an implementation manner, the specified duration may be 10ms, so after the first control terminal ESWIRE is pulled high for 10ms, the buck-boost converter (buck-boost converter) inside the second power supply module 120 is activated, and then , utilize the second inductor L2 to periodically store and release energy, and output the second voltage V02.
